enricobuehler	de7b8ac282	feat(android): video decode pipeline — NDK AMediaCodec → SurfaceView ... M4 Android stage 1 (video). Pull HEVC access units from the connector and render them to the SurfaceView entirely in Rust (NDK AMediaCodec → ANativeWindow) — no per-frame JNI, honoring the native-thread hot-path invariant. - crates/punktfunk-android: decode.rs (one-in/one-out AMediaCodec loop; in-band VPS/SPS/PPS so no out-of-band csd; dims from NativeClient::mode). SessionHandle now holds an Arc<NativeClient> + the decode thread; nativeStartVideo/nativeStopVideo. - clients/android: connect screen (host/port) + full-screen SurfaceView stream screen — surfaceCreated -> nativeStartVideo, leaving -> stop + close. Verified live (Android emulator -> m3-host on the LAN box, ABI v2): QUIC handshake, 8-round clock-skew sync, HEVC decoder configured at 1280x720, and the data plane delivered + fed all 299 access units (the punktfunk/1 NAT hole-punch worked through the emulator's SLIRP). Real-pixel render is pending a non-synthetic source: `m3-host --source synthetic` emits dummy transport payloads (not HEVC), so the decoder correctly produces nothing; `--source virtual` (a compositor on the host) is needed to verify decode-to-screen.

enricobuehler	79217eb93d	feat(android): scaffold the native Android client (Rust-heavy JNI bridge) ... Rust-heavy client model (like punktfunk-client-linux): a new cdylib crate crates/punktfunk-android links punktfunk-core and exposes the JNI seam; Kotlin (clients/android) owns only the Android-framework surface. Kotlin can't import the C header the way Swift can, so the bridge is written in Rust to reuse the Linux client's orchestration rather than re-port it. - crates/punktfunk-android: JNI bridge — abiVersion/coreVersion native-link proof + session connect/close handle; plane pumps stubbed for M4 stage 1. - clients/android: Gradle project — :app (Compose) + :kit (Android library with a cargo-ndk Exec task -> jniLibs). AGP 9.2 / Gradle 9.4.1 / Kotlin 2.3.21 / Compose BOM 2026.05.01 / compileSdk 37 / targetSdk 36 / minSdk 31, shipping arm64-v8a + x86_64. Phone + TV (leanback) installable. README rewritten. - .gitea/workflows/android.yml: CI mirroring apple.yml on a Linux runner. - punktfunk-core: switch rcgen to the ring backend so the whole quic tree is aws-lc-free (smaller client .so, cmake-free cross-compile; a win for all targets). Validated on this box: :app:assembleDebug -> APK with both ABIs; emulator first-light renders the bridge linked (core ABI v2) with logcat confirmation; clippy -D warnings + cargo fmt clean; core tests green on the ring backend.
